IMPROVEMENT IN MECHANICALA MOVEMENTS.

Specification forming part of Letters Patent No. 209,736, dated November 5, 1878 application filed October 16, 187B.

To all whom 'it may concern:

Be it known that I, ALBiN WARTH, of Stapleton, in the county of Richmond and State of New York, have invented a new and which I have described in my Patent N0.-

l79,375, dated June 27, 187 6.'

My present improvement consists in the combination, with` a working machine, of a swivel-arm, which forms the bearings for the shaft transmitting motion to said working machine a vertical shaft which connects with the swivel-arm by a bracket, a table which supports the work to be acted on by the working-machine, a carriage which supports the bearing of the vertical shaft, guide-rails for said carriage, which are secured to the worksupporting table, v two jointed arms which swing in vertical planes, and suitable belts and pulleys for transmitting motion from the drivingshaft tothe working machine, so that in moving the working machine over the table the jointed arms swing up and down between the carriage and the iixed standard which supports the driving-shaft, and thereby considerable room is saved, while the working machine can be freely moved over a comparatively long distance in either direction.

In the drawing, the letter A designates a table, which is intended to support the work to be acted upon by the working machine B. In the example shown in the drawing this machine carries a grinding-disk, such as may be used for finishing piano-tops, grinding marble slabs, or for performing other work of a similar nature; but other devices may be substituted for the grinding mechanism-such, for instance, as a mechanism for engraving, sawing, or cutting any material.

On one side of the table A are secured two rails, a b, one above and the other below, for

supporting a carriage, C, which is provided with wheels c, so that it can be easily pushed along on said rails in either direction. On the back of this carriage is firmly secured a bracket, d, which forms the bearing fora vertical shaft, e, and on the upper end of this shaft is rmly secured a jointed bracket, f, from which extends an arm, D, that carries the working machine B. The joint in the bracket f allows the arm D to swing up and down, so that the working machine can be raised from or depressed upon the table A, or the Vwork supported by said table; but inv some cases said bracket may be made rigid. Moreover, by means of the Vertical shaft e the arm D is adapted to swivel in a horizontal plane, so that the working machine can be moved over the table in a segmental path.

The swivel-arm'D forms the bearings for a shaft, g, which serves to transmit motion to the grinding-disk or other device carried by the working machine, and on which is mounted a pulley, k, which connects by a belt, i, with a pulley, j. This belt is carried down under guide-pulleys 7c', mounted on a horizontal shaft, which has its bearing in a standard, l, extending from the back of the carriage C, and the pulley j is mounted on a stud, k, which extends from the bracket d, that forms the bearing of the vertical shaft c. The pulley j is 'firmly connected to another pulley, m, from which extends a belt, n, over a pulley, o, which turns loosely on a stud, p, and to which is firmly connected another pulley, q, fromwhich extends a belt, r, over a pulley, s, mounted on the driving-shaft t.

The pulleys j and m turn loosely 011 the stud 7c, and this stud is connected with the stud p by an arm, E, that swings freely on both said studs.

The stud p is iirmly secured in the end of an arm, F, which swings freely on the drivT .ing-shaft t, and which carries a weight, G, for the purpose of balancing the weight of the pulleys o g, stud p, and arm E.

The driving-shaft t has its bearing in the top of a standard, H, which rises from the oor.

From this. description it will be seen that by the combined action of the swivel-arm D, the carriage O, and the joint-arms E F, the workin g machine can be freely and easily moved over the table in either direction, and

during the motions of the Working machine the arms E F swing' in vertical planes in the space between the table A and the standard H, which supports the bearing` ofthe drivingshaft.

1f the arms E F swing` in horizontal planes, much extra room is required, and if it is considered that in many cases these arms have to be made from eight to ten feet long, it will be seen that by my present improvement a great advantage is gained over the device described in my Patent No. 17 9,375.

Another advantage of my present device consists in the fact that the rails for the carriage are secured to the side of the table A.

I distinctly disclaim in this application everything shown and described in the abovenamed patent.

lVhat I claim as new, and desire to secure by Letters Patent, is

1. The combination, with a Working machine, B, of :a swivel-arm, which forms the bearings for the shaft transmitting motion to said Working machine, a vertical shaft which connects with the swivel-arm by a bracket, a table which supports the work to be acted on by the Working machine, a carriage which supports the bearing of the vertical shaft, guide-rails for said carriage, which are secured to the side of the Work-supportin,(2.` table, two jointed arms which swing in vertical planes, and suitable belts and pulleys for transmitting motion from the driving-shaft to the Worki n g machine, all constructed and adapted to operate substantially as and for the purpose set forth.

2. The combination, with the swivel-arm D, Working` machine B, table A, carriage C, and vertical shaft c, of a jointed bracket, f, to allow the Working machine to move toward and from the surface of the table, substantially as described.

In testimony that I claim the foregoing I hereunto set my hand and seal this 10th day of October, 1878.
